1. A batter hits a 0.140-kg baseball that was approaching him at 30.0 m/s and, as a result, the ball leaves the bat at 40.0 m/s in the direction of the pitcher.nthe ball remains in contact with the bat for 2.0 ms. What is the average force exerted by the bat?

2. Two objects approach eachother with velocities such that the total momentum of the masses is zero kgm/s, and undergo an elastic collision. Is the kinetic energy of each object the same before and after the collision?

3. An air track cart with mass m and speed v moving along an air track collides with a stationary cart with a mass m/3. After the collision the first car has a speed v/2.is the collision elastic?
